golfer,
Ask your dentist, doctor, or lawyer whom they play with, they are usually notorious slow-pay degens..unlike our founder Ken!
Find out where high stakes Poker is played locally
Join a country club, and/or ask some golf pros how they get down action
Find the best sports bars in your town, ask the barkeep whom the betting crowd is there
Pool halls always have small BMs
Car salesmen are degenerate parlay card bettors/MNF junkies, ask one
Look into local tv, police, or fed web archives, it often has records of BMs busted in the past
Check with some of your alumni chapter big athletic donation people, and odds are that some bet with the best locals
Any finer local Italian restaurant owner will know the A-list of local BMs by name, if not personally
Any Jewish deli owner could probably lead you to a good one
OTBs,etc..
The only edge a local has for you is that he may let you on games a few minutes after post when you get caught napping, free square-ups, credit(all the rope one would want to hang one self), longer duration open-ended parlays/teasers, and possibly softer numbers
If once you find a good one, and he never refers you forward to a larger one..it means he wants to keep you in his pocket.
He'll never have as many offerings nor 7 cent juice as does offshore.
People asking for locals on bulletin boards is second only to Borat's "wanting to make romance inside her" as far as making me chuckle.
